METHOD FOR WEIGHING AND TRANSPORTING DOUGH AND DOUGH DRUM

Description

[0001] The invention relates to a method for weighing and transporting dough according to the preamble of claim 1 and a dough drum for portioning dough according to the preamble of claim 5.

[0002] Various methods and devices, also known as dough dividing machines, are known from the prior art for portioning a required dough weight from a dough mass using the volume method. These devices typically use dough drums with a number of dividing pistons into which dough is pressed and thus portioned. The dividing pistons, also called weighing pistons, are controlled by means of cam lever systems or mechanical systems.

[0003] Devices and methods for weighing and transporting dough are known from US Patent 3,125,039 A (HAUG, F ET AL) of March 17, 1964, US Patent 5,897,203 A (KOCK GERD [DE]) of April 27, 1999, and US Patent 2007 / 248711 A1 (BRUNNER KARL HEINZ [US] ET AL) of October 25, 2007. The devices comprise a weighing device with a weighing slide that is controllably movable back and forth in a discharge channel. Furthermore, the devices comprise a dough drum that is pivotable or rotatable about its axis, which has at least one receiving chamber for receiving dough and, in each receiving chamber, a weighing plunger guided linearly in the radial direction of the dough drum within the receiving chamber, which is adjusted by an adjusting device in the receiving chamber. The devices also include a knitting drum with a number of knitting chambers evenly distributed around the circumference of the knitting drum.In a weighing step, a defined volume of dough is weighed and / or pressed into at least one receiving chamber via the output channel using the weighing slide, whereby the balanced dough volume is specified and set by means of radial adjustment of the weighing plunger.In a transport step, after reaching the predetermined filling volume and / or filling pressure in the receiving chamber, the weighing slide is stopped and the dough drum is pivoted into a transfer area until the respective dough-filled receiving chamber is positioned opposite one of the working chambers, so that the dough can be transferred from the receiving chamber to the respective working chamber, and in an ejection step, the weighing plunger is adjusted in the receiving chamber such that the dough is ejected from the receiving chamber and transferred to the working chamber, wherein the adjusting device comprises at least one linear drive that adjusts at least one weighing plunger simultaneously and uniformly in a controlled manner, wherein the stroke of the weighing plungers is controlled by the adjusting device and is changed depending on the consistency of the dough or according to a specification, possibly according to a stored template.

[0004] The disadvantage of systems known from the prior art lies in the fact that the processes to be controlled are defined by mechanical elements, and thus the timing of the weighing stamp's movement cannot be changed, or only to a limited extent. This leads to limitations in the weight range of the dough pieces that can be weighed, a restriction in the types of dough that can be used, and therefore a reduction in production output.

[0005] The object of the present invention is therefore to create a method of the type mentioned at the outset that makes it possible to process a wide range of doughs and dough volumes.

[0006] This problem is solved by the characterizing features of claim 1.

[0007] By using a linear drive to adjust the weighing dies, it is possible to modify the timing and adjustment speeds of the weighing die(s) by adjusting the linear drive's motion kinematics. For example, increasing the weighing die stroke allows a larger volume to be introduced into the receiving chambers, thus changing the dough volume or weight weighed into the dough drum or balanced by the weighing device. Furthermore, the flexible adjustment of the linear drive enables the definition of various complex movement patterns for the weighing dies, facilitating gentle processing of a wide range of doughs and dough weights. The indexing bar allows for the simultaneous adjustment of several or all weighing dies, creating a uniform adjustment profile.Furthermore, the indexing bar allows for variations in the number, spacing, and dimensions of the weighing pins without requiring the adjustment mechanism or any parts thereof to be replaced. The linear drive comprises an electromechanical drive and at least one actuator, which enables the adjustment of a number of weighing pins via the indexing bar. The actuator converts the rotary motion of the electromechanical drive into a linear motion.

[0008] The inventive method can be further improved by drawing in the weighing plunger in a controlled manner during the transport step while pivoting the dough drum into the transfer area and increasing the volume in the receiving chamber in order to reduce the dough load or dough pressure.

[0009] Relieving the dough after the weighing step or during transport prevents it, especially with highly expansive doughs, from overflowing the receiving chamber and allows it to return to its original internal pressure level. Particularly with low-density doughs, such as those with large pores or a high expansion tendency, this pressure relief prevents the dough from sticking too strongly to the weighing dies and also enables gentle processing of the dough.

[0010] The dough consistency can be further advantageously influenced by inserting the weighing stamps into the receiving chambers before weighing the dough, depending on the dough consistency and / or firmness, or by pressing the dough against the weighing stamps using the weighing slide and then adjusting the weighing stamps simultaneously with the weighing slide.

[0011] By inserting the weighing stamps before the filling process, the structure of soft and delicate doughs is protected, resulting in optimal dough quality. For firmer doughs, such as pretzels or doughs requiring pressure, the weighing pusher first presses the dough against the weighing stamp, thus creating a predetermined pressure. The weighing stamp is then adjusted synchronously with the pusher movement, ensuring consistent pressure on the dough. This maintains the desired dough quality and guarantees high weight accuracy for the precisely balanced dough pieces.

[0012] To advantageously eject the dough from the receiving chamber depending on the dimensions of the weighing punches, it can be provided that the ejection step begins during the transport step, wherein the time of commencement and / or the duration of the ejection step is adjusted depending on the dimensions of the weighing punches, wherein, with four weighing punches of large diameters, the ejection step begins later, in particular after a larger pivoting angle of the dough drum, and is carried out at a high adjustment speed of the weighing punches, and / or wherein, with weighing punches of small diameters, the ejection step begins earlier, in particular at a smaller pivoting angle of the dough drum, and is carried out at a lower adjustment speed of the weighing punches.

[0013] Furthermore, it is an object of the present invention to create a dough drum of the type mentioned above with which a wide range of different doughs can be portioned or processed and which requires little setup effort.

[0014] This problem is solved by the characterizing features of claim 5.

[0015] By installing a linear drive in the dough drum, it is possible to vary the timing and stroke of the weighing stamps and adapt them to the specific requirements of the dough, depending on the processing stage. Furthermore, the adjustable control kinematics of the linear drive allow for different portioning methods and processing steps, enabling the processing of a wide range of doughs without requiring machine retooling. Additionally, the pressure in the receiving chamber can be adjusted according to the dough's requirements by adjusting the weighing stamps via the linear drive. The linear drive comprises an electromechanical drive and at least one actuator, which allows for the adjustment of a number of weighing stamps via the indexing bar. The actuator converts the rotary motion of the electromechanical drive into a linear motion.

[0016] Particularly advantageous embodiments of the device are defined in more detail by the features of the dependent claims: One advantageous embodiment provides that the electromechanical drive includes position detection.

[0017] It is advantageously provided that the actuator is designed as a spindle drive, lifting crank, toggle lever, hydraulic cylinder or pneumatic cylinder.

[0018] In order to be able to use a variety of different weighing stamps, it is provided that the dough drum includes at least one interchangeable strip which can be detachably inserted or attached to the housing, with the receiving chambers for the portions of dough to be portioned being arranged in the interchangeable strip.

[0019] In an advantageous embodiment, the adjusting device comprises one linear drive for each weighing stamp, wherein each weighing stamp, in particular all weighing stamps, are adjustable in the respective receiving chambers simultaneously and / or uniformly, controlled by the respective linear drives, wherein the stroke and / or the adjustment speed and / or the adjustment time of the weighing stamps is adjustable controlled by the respective linear drive.

[0020] By using an interchangeable bar, it is possible to easily replace the weighing stamps inserted into the interchangeable bar or the receiving chambers of the interchangeable bar by removing the interchangeable bar from the housing and inserting a different interchangeable bar, for example with a different stamp spacing or different stamp sizes.

[0021] An advantageous application of the device according to the invention provides that a device comprises a weighing device with a weighing slide which is controllable and movable back and forth in an output channel, and a dough drum according to the invention which is pivotable or rotatable about its axis.

[0022] Further advantages and embodiments of the invention will become apparent from the description in the accompanying drawings.

[0023] The invention is shown schematically in the drawings below with reference to particularly advantageous, but not limiting, embodiments and is described by way of example with reference to the drawings: Fig. 1 shows a sectional view of a dough drum according to the invention. Fig. 2 The figure shows a device according to the invention with a weighing device, dough drum and working drum in cross-section. Fig. 3 bis 8 shows a preferred embodiment of the method according to the invention.

[0024] In Fig. 1 A dough drum 3 according to the invention for portioning dough is shown in a sectional view, the section being drawn along the width of the dough drum 3. The dough drum 3 comprises a housing 8, which is designed in the shape of a drum. The dough drum 3 further has eight receiving chambers 31, which extend radially along the dough drum 3. A weighing plunger 32 is arranged in each receiving chamber 31, which is guided linearly within the receiving chambers 31. The weighing plungers 32 are adjustable linearly within the receiving chambers 31 in the radial direction of the dough drum 3. As shown in Fig. 1 As shown, when the adjusting device 6 is moved towards the interior of the dough drum 3, the weighing stamps 32 create a space in the receiving chambers 31 into which dough can be placed. The weighing stamps 32 rest on an adjusting device 6, which allows them to be adjusted radially along the dough drum 3. The adjusting device 6 has a linear drive 61, which moves the weighing stamps 32—in this embodiment, all of them. The linear drive 61 allows the weighing stamps 32 to be moved simultaneously and uniformly within their respective receiving chambers 31. The stroke of the weighing stamps 32, their adjustment speed, and / or the timing of their adjustment are all controlled by the linear drive 61 and can be set according to the required process parameters. As shown in Fig. 1 As shown, the adjusting device 6 can optionally include a partial bar 33, which is adjustable by means of the linear drive 61. The partial bar 33 is prismatically shaped, and the weighing pins 32 are in contact with the partial bar 33, so that the adjustment of the partial bar 33 by means of the linear drive 61 or the adjusting device 6 leads to an adjustment of the weighing pins 32 in the receiving chambers 31.

[0025] The weighing stamps 32 can rest against, be positioned against, or be connected to the dividing bar 33. For example, the weighing stamps 32 can rest against the dividing bar 33 when dough is pressed into the receiving chambers 31.

[0026] In this embodiment, the linear drive 61 has an electromechanical drive 62 which includes position detection. The linear drive 61 further has two actuators 63, which are designed as spindle drives. The electromechanical drive 62, which is, for example, an electric motor, drives a nut of each of the spindle drives or actuators 63, thereby linearly adjusting the spindle of each spindle drive. The spindles of the spindle drives or actuators 63 are connected to the indexing strip 33, whereby the adjustment of the spindles of the actuators 63 results in a linear adjustment of the indexing strip 33 along the Fig. 1 The adjustment directions are indicated by the double arrow. This is achieved through the actuators 63, as e.g. in the [reference to the diagram]. Fig. 1 In the illustrated embodiment, the spindle drives convert the rotary motion of the electromechanical drive 62 into a translational or linear motion.

[0027] As in Fig. 1 As shown, the dough drum 3 can optionally include an interchangeable strip 7, which can be detached, inserted, or plugged into the housing 8. The interchangeable strip 7 has a number of receiving chambers 31, which are arranged in a straight line one behind the other within the interchangeable strip 7. By using or providing an interchangeable strip 7, the weighing pins 32, which are arranged in the receiving chambers 31, can be easily exchanged by inserting corresponding interchangeable strips 7 with different dimensions of weighing pins 32 or differently sized receiving chambers 31 into the housing 8. Optionally, the adjustment of the weighing pins 32 can also be carried out by other linear drives known from the prior art, such as linear motors, hydraulic or pneumatic cylinders, or the adjustment device 6 can include such linear drives.Alternatively, it may also be provided that the adjusting device includes 6 rotary drives which convert a rotary movement into a linear adjusting movement, such as crank or toggle lever systems, racks and the like.

[0028] Fig. 2 Figure 1 shows a dough drum 3 according to the invention in a device for portioning and processing dough. The device has a weighing device 20, which includes a weighing slide 2 that is linearly movable back and forth in a discharge channel 31. Furthermore, a forming drum 4 is provided, which has a number of forming chambers 41 that are evenly distributed around the circumference of the forming drum 4. The dough drum 3 is positioned relative to the forming drum 4 such that dough, which is introduced into the receiving chambers 31 of the dough drum 3, can be transferred from the receiving chamber 31 of the dough drum 3 into the forming chambers 41 of the forming drum 4 in a transfer area 5. The dough drum 3 and the forming drum 4 are each rotatable or pivotable on their axes, so that the receiving chambers 31 can be positioned relative to the forming chamber 41.

[0029] The following describes a method according to the invention using a preferred embodiment: As in Fig. 3 As shown, in a weighing step, dough is discharged from the weighing device 20 via the output channel 22 by means of the weighing slide 2. During the weighing step, the dough drum 3 is positioned relative to the weighing device 20 such that the receiving chamber 31 points towards the output channel 22 of the weighing device 20. The adjusting device 6 or the linear drive 61 moves the weighing plunger 32 in the receiving chamber 31, thus creating space for the dough. The weighing slide 2 then presses the dough located in the output channel 22 into the space created by the weighing plunger 32 in the receiving chamber 31, thereby introducing a volume portion of the dough, defined by the position of the weighing plunger 32, into the receiving chamber 31. The radial adjustment of the weighing plunger 32 by means of the linear drive 61 or the linear drive 61 allows for precise control of the volume of dough.By means of the adjusting mechanism 6, a defined quantity of dough is weighed from the output channel 22 of the weighing device 20. After reaching the predetermined filling volume or filling pressure of the dough in the receiving chamber 31, the weighing slide 2 is stopped and the dough drum 3 is transported in a single step ( ). Fig. 4 In this embodiment, the dough drum 3 is pivoted or rotated clockwise. During the transport step, the dough drum 3 with the receiving chamber(s) 31 is pivoted into the transfer area 5, and the respective dough-filled receiving chamber 31 is positioned relative to one of the working chambers 41 of the working drum 4 so that the dough can be transferred from the receiving chamber 31 to the respective working chamber 41. Upon reaching the transfer area 5, the weighing plunger 32 is moved radially within the receiving chamber 31 by the linear drive 61 or the adjusting device 6 in an ejection step, so that the dough is pressed or squeezed out of the receiving chamber 31. As the dough is ejected from the receiving chamber 31, the working chamber 41, positioned opposite the receiving chamber 31, is filled with the quantity of dough contained in the receiving chamber 31.The linear drive 61, which adjusts the weighing stamps 32 (in this embodiment, all weighing stamps 32) simultaneously and uniformly, makes it possible to change the stroke and / or the adjustment speed and / or the adjustment timing of the weighing stamps 32 in a controlled manner, depending on the consistency of the dough or according to a template stored in the control unit of the linear unit 61. For example, by changing the stroke of the weighing stamps 32 using the linear drive 61, the volume of dough balanced by the weighing slide 2 into the receiving chamber 31 can be changed and thus predetermined.

[0030] Optionally, in the inventive method, the weighing plunger 32, or all weighing plungers 32, can be retracted into the transfer area during the transport step while the dough drum 3 is pivoted, i.e., moved towards the center of the dough drum 3. This increases the volume in the receiving chamber 31 and thus reduces the dough load or the pressure acting on the dough in the receiving chamber 31. The retraction movement of the weighing plunger 32 provides more space for the dough, and, for example, expansive doughs that tend to expand after being weighed from the weighing device 20 can be retained in the receiving chamber 31 without overflowing or protruding completely or partially. This results in optimal pressure distribution in the balanced dough and thus positively influences the quality of the dough.

[0031] Furthermore, the position of the weighing pistons 32 can be changed during the weighing step, depending on the dough consistency and / or firmness. For example, it can be provided that the weighing piston 32 is already moved towards the center of the dough drum 3 before the weighing step or the weighing stroke of the weighing slide 2, thus releasing the volume to be weighed into the receiving chamber 31 before the filling process or weighing step. This results, for example, in optimal dough quality, as the dough is subjected to only minimal weighing pressure. Alternatively, it can be provided that the weighing piston 32 is only fully or partially extended during the weighing step, i.e., it does not release any space in the receiving chamber 31 at the beginning of the weighing step.When the weighing slide 2 in the output channel 22 is moved towards the receiving chamber 31, thus applying pressure to the dough, this creates a counter-pressure on the dough, allowing a constant pressure to be generated. Only after a predetermined dough pressure has been reached is the weighing plunger 32 then moved towards the center of the dough drum 3 by the adjusting device 6 or linear drive 61, according to the preset weighing volume or pressure. This gradually opens the space in the receiving chamber 31 for the dough, which is then pressed into the receiving chamber 31 by means of the weighing slide 2. This optional step makes it possible to keep the dough under constant pressure, which, for example, leads to better quality with firm doughs such as those used for pretzels, and ensures good weight accuracy of the balanced dough pieces.

[0032] Furthermore, in the method according to the invention, it can be provided that the ejection step begins during the transport step. As in the Fig. 5 and 6 As shown, depending on the dimensions of the weighing stamp 32, pressure can be generated on the dough at different adjustment angles α, and the ejection process can be initiated. For example, with small weighing stamps ( Fig. 5 ) the ejection process can begin even at small adjustment or pivoting angles α of the dough drum 3, since the cross-section of the receiving chambers 31 or the weighing plungers 32 has already passed any obstacles such as deflection rollers 45. Thus, with weighing plungers 32 with small diameters, the ejection step can begin earlier than with weighing plungers 32 with large diameters ( Fig. 6 ).

[0033] Similarly, depending on the dimensions of the weighing stamps 32 or the balanced quantity of dough, the end of the ejection step can be modified depending on the required adjustment speed of the weighing stamps 32 or the consistency of the dough. The flexible adjustment of the ejection speed or ejection timing allows a large number of different weighing stamps 32 to be operated with the same adjustment device or indexing bar 33, thereby increasing the variability of the dough drum 3 or the method according to the invention. For example, with one and the same dough drum 3, the ejection speed in the ejection step can be changed according to the requirements of the individual production times in order to achieve optimal dispensing of the dough from the receiving chambers 31 into the working chambers 41. Furthermore, the adjustment of the individual process parameters is not coupled to mechanical elements and can thus be carried out with one and the same adjustment device 6 or indexing bar 33.The linear drive 61 can be adjusted as needed.

[0034] As in the Fig. 7 and 8 As shown, the retraction movement of the weighing pins 32 during the transport process can also be advantageously adapted to the diameter of the weighing pins 32. For example, as shown in Fig. 7 As shown, with smaller weighing stamps 32, the retraction process begins earlier because the receiving chamber 31 no longer corresponds with the output channel 22 of the weighing device 20 at smaller rotation angles β. With larger weighing stamps 32, as in Fig. 8 As shown, the timing of the retraction movement of the weighing stamp 32 can be chosen differently in relation to small weighing stamps 32, so that even when varying the stamp diameters, it can be ensured that no dough is drawn from the weighing stamp 32 into the receiving chamber 31 during the retraction movement.

[0035] Thus, depending on the nature of the dough, whether it has a high or low specific weight, a high swelling behavior, or is firm or loose, the process parameters in each individual step of the weighing process can be adapted to the requirements of the dough, thereby ensuring the highest quality throughout the entire weighing and processing process of the dough, thanks to the dough drum 3 according to the invention.

[0036] Alternatively, the dough drum 3 may also have several interchangeable strips 7 distributed around its circumference, so that during rotation of the dough drum 3 about its own axis, several receiving chambers 31 arranged one behind the other along the interchangeable strip 7 can be brought into correspondence with the weighing device 20 or the working chambers 41 of the working drum 4. It may also be provided that, as in the Figuren 1 bis 8As shown, the dough drum 3 is designed as a so-called dough dividing drum, each comprising only one interchangeable strip 7 that can be inserted or attached into the housing 8 of the dough drum 3. Such an interchangeable strip 7 can have one or more receiving chambers 31, which are advantageously arranged in a straight line one behind the other along the longitudinal extent of the interchangeable strip 7. The receiving chambers 31 of the respective interchangeable strip 7 can be of the same size, and identical weighing dies 32 can be arranged in each receiving chamber 31.

[0037] In alternative embodiments not shown, the adjusting device 6 comprises a linear drive 61 for each weighing die 32. The linear drives 61 each adjust one of the weighing dies 32 and can be adjusted synchronously via a control unit. Alternatively, it can also be provided that the weighing dies 32 each have different dimensions and that a linear drive 61 is provided for each dimension of the weighing dies 32, thereby allowing the individual adjustment movements of the weighing dies 32 or the different dimensions of the weighing dies 32 to be controlled differently.
